Configure LogTape so Fedify federation logs surface

[malkoG]

Summary

Fedify routes all of its logging through LogTape, and LogTape discards every record until a sink is configured. Moim never configured one, so inbox/outbox traffic, HTTP Signature failures, and unhandled activity types were invisible. This wires a console sink controlled by FEDIFY_LOG_LEVEL (default info) and attaches an AsyncLocalStorage so Fedify's per-request log context is carried through.

Why

• Debugging federation was blind
  • While investigating a Mastodon → Moim FeatureRequest that stayed "pending", there was no way to see whether the request arrived, failed signature verification, or was rejected; the root cause (Missing actor) only became visible after this change.
• Fedify warns without context storage
  • Fedify calls withContext() per request; without contextLocalStorage LogTape logs Context-local storage is not configured twice per request and drops the context.
• Keep page views quiet
  • Fedify logs a 404 warning under fedify.federation.http for every non-federation path it hands back to TanStack, i.e. every page view. That category is held to error unless the level is debug/trace, where seeing every request path is the point.

Commit History

• Configure LogTape so Fedify federation logs surface : adds src/server/logging.ts, FEDIFY_LOG_LEVEL env + docs, imports the config first in server-entry.ts

Test Plan

• tsc --noEmit and oxlint pass
• With FEDIFY_LOG_LEVEL=debug, an inbox POST shows fedify.federation.inbox / fedify.sig.* lines and no logtape.meta warnings
• At the default info level, page views produce no fedify.federation.http 404 warnings
• Confirm log volume is acceptable on the production container at info
